3.2. Connector for Power Supply
Connector used: CN1: MOJ-D14 (Iizuka Electric)
Electrical Specifications
Input volt a ge: 7 to 15 V DC
Current at non printing: 0.15 A average
Current at printing: 0.80 A average (approx. 7.5 A at peak)
The above val u e is at temperature of 25 °C a nd normal humid it y.
Average current is the value with print rate of 12.5%.
The values vary with the printing condition, environment of use, operating conditions, etc.
Precautions
1. Before co nnecting or discon ne cting a connecto r, make sure the prin ter power is turned off.
2. Always use t he power voltage with i n the specified range.
Caution
• When the power supply other than specified is used, bad effect may occu r on printing operation, etc.
When the printer is operated continuously, electronic components in the board may generate heat. Use
the printer pa ying ful l at tent io n to heat dissi pat io n.
• When the power supply with insufficient peak current is used, degradation of print quality may occur
dependi ng on the printing st ate.
• Be sure to prepare for easy tur ni ng off the power sup ply in ca se of power failu re.
• Power supply with var ious kinds of protect ive circui ts such as ove rvolta ge protec tion and ove rcurrent
protection is recommended.
• If any abnormality such as abnormal odor is sensed during operation, turn the power supply off
quickly.

Caution
(1) Fo r t he POWER and SEL LEDs, a res is tance of 330 Ω is provided at t he circuit side to adjust the
current to 10 mA. Use the LED with forward voltage of about 2 V. Do not use LED exceeding 10
mA. Otherwise, the control may be damaged.
(2) T he input terminals for LF-SW and SEL-SW have the above cir c uit. Though a cerami c capacitor is
inserted in the circuit for preventing chattering, large chattering may occur depending on the switch.
(3) Apply insulati o n processing to th e terminal not in us e to prevent the end of the cable from cont acting
other terminal or parts.

* The above circui t i s an example of refle ct ion type photo interrupter.
When using the above sensor, allow a clearance of approx. 1 mm from paper.
As the sensor used is different in electrical characteristics, use the sensor after fully recognizing it.
* The voltage dete ction range of the b o a r d (between 2 and 3) is as fo l lows:
0 to 0.4 V: With paper
1 V or more: Wit hout paper
Detection status other than the above is out of warranty.
